 xlnt is a c++ library that reads and write XLSX files. The API is roughly based on openpyxl, a python XLSX library. It is still very much a work in progress, but I expect the basic functionality to be working in the near future.
 
+Usage
+----
+```c++
+xlnt::workbook wb;
+xlnt::worksheet ws = wb.get_active_sheet();
+ws.cell("A1") = 5;
+ws.cell("B2") = "string data";
+ws.cell("C3") = "=RAND()";
+ws.merge_cells("C3:C4");
+ws.freeze_panes("B2");
+wb.save("book1.xlsx");
+
+xlnt::workbook wb2;
+wb2.load("book2.xlsx");
+wb2["sheet1"].get_dimensions();
+for(auto &row : wb2["sheet2"])
+{
+    for(auto cell : row)
+    {
+        std::cout << cell.to_string() << std::endl;
+    }
+}
+```
